ABSTRACT

Disclosed is a portable mobile communications device and method that can create and store a transaction log of data exchanged over a near field RF communication system. A near field RF communication data transaction is performed. A transaction log record of the just performed near field RF communication data transaction is then created and stored in a transaction log database. A transaction log record is created by obtaining data pertaining to the transaction that uniquely identifies the transaction and its context and filling fields of the transaction log record with the relevant data obtained. The transaction log database is made accessible to the user for review and manipulation.

BACKGROUND OF THE INVENTION

Portable mobile communications devices such as mobile phones are becoming more sophisticated and include many new features and capabilities. Many portable mobile communications devices include a secondary near field RF transceiver such as, for instance, Bluetooth™ or the like. The near field transceiver is designed to provide device-to-device communications that are limited in range. In essence, near field RF systems are designed to eliminate the need for wires or cables between communicating devices. Examples of use include, wireless headsets, file transfers, electronic commerce, etc.

Many of the use cases involve sharing, sending, receiving or exchanging sensitive personal data. This includes personal financial account data that identify credit cards, debit cards, and perhaps even bank accounts. It would be advantageous to know when such information was sent and to whom in order to verify the integrity of certain transactions. This goal can be achieved with the creation and maintenance of a transaction log. Such a log would allow the portable mobile communications device owner to view detailed data pertaining to transactions to verify that a given transaction was indeed intended.

BRIEF SUMMARY OF THE INVENTION

Disclosed is a portable mobile communications device, method, and computer program product that can create and store a transaction log of data exchanged over a near field RF communication system. A near field RF communication data transaction is performed by establishing a near field RF communication connection between the portable mobile communications device and another similarly equipped wireless device, exchanging data between the portable mobile communications device and other similarly equipped wireless device over the established near field RF communication connection, and terminating the established near field RF communication connection between the portable mobile communications device and the other similarly equipped wireless device.

A transaction log record of the just performed near field RF communication data transaction is then created and stored in a transaction log database. A transaction log record is created by obtaining data pertaining to the transaction that uniquely identifies the transaction and its context and filling a plurality of fields of the transaction log record with the relevant data obtained. The transaction log database is made accessible to the user for review and manipulation.

The plurality of fields of the transaction log record include universal transaction fields that identify the sending wireless device involved in the data exchange, the receiving wireless device involved in the data exchange, the geographic location of the near field RF communication data transaction, and the date and time of the near field RF communication data transaction.

For commercial transactions, the plurality of fields of the transaction log record also include financial data such as a financial account associated with the near field RF communication data transaction, a monetary amount associated with the near field RF communication data transaction, a field that identifies the vendor associated with the near field RF communication data transaction. A vendor is an entity that sells or otherwise provides goods or services such that a portable mobile communications device can communicate with the “vendor” electronically to purchase or otherwise obtain the goods or services.

For file transactions, the plurality of fields of the transaction log record also include file data such as a field that identifies a transaction file identifier containing data pertaining to a file name identifier, a file type identifier, a file size identifier, and a file location identifier.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description of embodiments refers to the accompanying drawings, which illustrate specific embodiments of the invention. Other embodiments having different structures and operations do not depart from the scope of the present invention.

FIG. 1 is an illustration of a portable mobile communications device 100 and a variety of other wireless devices that can be equipped to communicate with the portable mobile communications device over a near field RF communication system. The portable mobile communications device 100 can take a variety of forms including but not limited to, a cellular phone operable on any of the numerous cellular wireless RF protocols including but not limited to, GSM and CDMA. The portable mobile communications device 100 is further equipped with a near field RF communication transceiver such as, for instance, a Bluetooth™ module. Other near field RF communication systems are also compatible and operable with the present invention.

The portable mobile communications device 100 can utilize its near field RF communication transceiver to communicate with other similarly equipped wirelessly enabled devices including, but not limited to, a wireless smartphone 110, a wireless information access point 120, a wireless personal digital assistant (PDA) 130, a wireless enabled point-of-sale (POS) device 140 (e.g., a computerized cash register), and other mobile phones 150. The near field RF communication system becomes operable when the portable mobile communications device 100 is brought into proximity of another similarly equipped device.

In the case of Bluetooth™, upon each device discovering the other, an RF connection can be established that allows data to be exchanged between the two devices. In other near field RF communication systems, one device can simply broadcast data to any device capable of receiving and processing the data and await some type of acknowledgement from the receiving device.

FIG. 2 is a block diagram of certain components of a portable mobile communications device 100 according to the present invention. Illustrated within the portable mobile communications device 100 is a near field RF communication module 210, a processor 220, a near field RF communication transaction log application 230, and data storage 240. The near field RF communication module 210 is used to establish and carry out data exchanges wirelessly over relatively short ranges between the portable mobile communications device 100 and another similarly equipped wireless device. The processor 220 is coupled with the other components and provides the system with computer processing capabilities in order to manage and carry out instructions pertaining to the creation and maintenance of transaction log records in a transaction log. The near field RF communication transaction log application 230 is a software application that is run by the processor 220 and provides the instructions used by the processor 220 to control the creation and maintenance of transaction log records in a transaction log. Data storage 240 provides memory space that is accessible by the processor 220 and the near field RF communication transaction log application 230 and is used to store transaction log records.

FIG. 3 is a flowchart illustrating a method for creating a transaction log within the portable mobile communications device that records data exchanges over the near field RF communication system. Creating and maintaining a transaction log of data exchanges broadly implies a two step process. The first step is to actually perform a data exchange. The second step is to memorialize aspects of the data exchange in the form of a transaction log record. A collection of transaction log records form an overall database that is referred to as the transaction log.

In step 310, a near field RF communication connection is established between the portable mobile communications device 100 and another similarly equipped wireless device. The exact mechanisms of creating this connection are left to the devices themselves and whatever particular near field RF communication system is being utilized. In step 320, data is actually exchanged between the two devices. A data exchange can take many forms depending on the format of the data being exchanged. A typical data exchange identifies one device as a sender and the other device as a receiver. The sending device will package and send data over the near field RF communication system to the receiving device. The receiving device will typically reply with an acknowledgement of sorts indicating the status of the transaction. A device can be a sender, a receiver, or both for a given transaction. In step 330, the near field RF communication connection between the two devices is terminated upon completion of the desired transaction. The three steps just presented constitute the process of exchanging data between the portable mobile communications device 100 and another wireless device. Step 340 describes creating a transaction log record (see, FIG. 4) of data exchanged between the portable mobile communications device 100 and the other wireless device. Lastly, step 350 describes locally storing the just created transaction log record in a transaction log database maintained on the portable mobile communications device 100. The transaction log record is created by gathering data pertaining to the exchange while the exchange is occurring and immediately afterward and is more fully described below.

The transaction log record can also or alternatively be stored remotely on another device to provide a back-up copy of all transaction log records. This can be achieved by sending the just created transaction log record to another device using the cellular RF module to a network storage device within the network infrastructure, a local RF transceiver such as Bluetooth™, an infrared connection, or a direct cable connection.

FIG. 4 is an illustration of an example of the data contained in a transaction log record 400. A transaction log record 400 is comprised of data that provides a context for the data exchange it represents. The record includes many types of fields that can be indexed by the user when later reviewing the transaction log database. There are many reasons for performing a near field RF data exchange. Each data exchange is unique in some way whether it is due to the time/date stamp of the transaction, the content of the data, the geographic location of the transaction, or a unique identifier of the sending and receiving wireless devices. A transaction log record 400 according to the present invention memorializes as much information about a near field RF transaction as it can.

The record about to be described as referring to FIG. 4 is not intended to be all encompassing, however. Others skilled in the art may include additional fields associated with a transaction that are not necessarily contemplated in this disclosure but still fall squarely within the framework of the present invention.

The first four fields illustrated in the transaction log record 400 of FIG. 4 are common to virtually every near field RF transaction because they are focused on device data, time/date stamping, and geographic positional data. This type of data is present for every near field RF transaction. Thus, the transaction log record 400 obtains a sending device identifier 410 and a receiving device identifier 420 that uniquely identify the wireless devices involved in a particular transaction. The transaction log record 400 further includes temporal and special records that record when and where the transaction took place. These are a location identifier 430 and a time/date stamp field 440. The location identifier can be obtained by a GPS type module if the mobile device is so equipped or via some other methodology. If there is no ‘fine’ positioning data available, the transaction log record 400 can at least attach a base station identifier to give a ‘coarser’ idea of the geographic location of the portable mobile communications device 100.

This can be valuable if a dispute arises as to a commercial transaction that is said to have occurred in a location that the portable mobile communications device 100 could not possibly have been in due to the basestation identifier associated with the transaction. While a basestation identifier has nothing to do with the actual transaction, since the near field RF module handles that, it can still provide valuable contextual data about the transaction.

The remaining fields in the transaction log record 400 are more closely associated with the content of the data transaction. For instance, it is becoming more common to use near field RF equipped devices in financial transactions to purchase goods or services from commercial enterprises. In such transactions, the portable mobile communications device 100 is provisioned with financial data such as, for instance, credit card account data, bank account debit card data, and/or specific vendor credit data. During a near field RF commercial transaction, the portable mobile communications device 100 is used to ‘pay’ for goods or services by sending specific financial data to a POS device (see, FIG. 1, reference numeral 140 for instance).

The transaction log record 400 will memorialize aspects of commercial transactions as a way to provide the user a back-up copy of transactions if ever a dispute arises. To that end there is a field for an account identifier 450 that identifies to which financial account the transaction was posted, an amount field 460 that indicates the amount of money was involved in the transaction, and a vendor identification data field 470 that provides as much information about the vendor as can be obtained including, but not limited to, vendor (store) name, store number, store address, sales associate responsible for the transaction, etc.

Another type of near field RF transaction may involve sending and/or receiving data files to/from another wireless device. This type of transaction encompasses exchanging media content files such as, but not limited to, audio files (MP3 or the like), video files (JPEG, MPEG, or the like), text files (e.g., Word, Excel, Powerpoint, etc . . . ), personal files such as contact data from a phonebook database, or the like. For these types of near field RF transactions, the transaction log record 400 will include a transaction file identifier field 480 that identifies things like a file name, a file type, a file size, the local address from which the file was obtained, etc.

FIG. 5 is a flowchart illustrating a method of examining and manipulating the records in a transaction log. The transaction log itself is a database of individual transaction log records 400 that are stored in data storage component 240 within the portable mobile communications device 100. The near field RF communication transaction log application 230 also provides a means for accessing, reviewing, and manipulating the transaction log records 400 in the transaction log database.

In step 510, the portable mobile communications device user can access the transaction log database via the user interface of the portable mobile communications device 100 and the near field RF communication transaction log application 230. In step 520, a list of the currently saved transaction log records 400 is displayed on the portable mobile communications device display. The default view of the displayed transaction log records 400 is presented according to the date/time stamp field of each transaction log record meaning that the transaction log records 400 on list are displayed from the most recent to the oldest.

In step 530, the list of transaction log records can be manipulated. Two types of transaction log record manipulation are described. In step 540, the user can ‘sort’ the transaction log records according to a field or parameter other than the default (date/time stamp). This allows the list to be reconfigured based on, for instance, vendor name, file name, file type, transaction amount, etc.

Perhaps the user is not sure that a particular transaction that occurred with a particular vendor has been accurately recorded by the vendor in a recently received statement. The user can access the transaction log database and sort the list according to the vendor name in an attempt to match the transaction log record on the portable mobile communications device 100 with the transaction recorded on the statement.

Or, the user can sort the list according to a file name to determine which devices were sent a particular file and when. There are numerous practical sorting scenarios that can be contemplated by a user and performed by the intelligence associated with the present invention.

In step 550, the user is provided the ability to selectively delete individual or grouped transaction records. A purging function can be incorporated into the near field RF communication transaction log application 230 that will purge transaction records that are of a certain age. This feature can be overridden by the user entirely or selectively by setting a parameter for a particular transaction record to be undeletable until otherwise specified.

Those skilled in the art may devise other transaction manipulation scenarios that are not specifically enumerated herein but which fit within the framework provided by the disclosure of the present invention.

As will be appreciated by one of skill in the art, the present invention may be embodied as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present invention may take the form of a computer program product on a computer-usable storage medium having computer-usable program code embodied in the medium.
